BK/AGC-V-1-R Equivalent & Substitute Parts

Part Overview

The BK/AGC-V-1-R is a 1 A, 250 V AC/DC fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This through-hole component features a 3AB, 3AG package format with dimensions of 1/4" x 1-1/4" (6.76mm x 32.82mm). The part maintains active product status and is RoHS3 compliant with CSA and UL approval certifications.

Identifying equivalent and substitute parts is necessary when the primary part experiences supply constraints, extended lead times, or inventory depletion. Substitute components must maintain electrical and mechanical compatibility within the specified parameters to ensure circuit protection performance and system reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/AGC-V-1-R is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)

The substitute part 0318001.HXP (Littelfuse Inc., Series 318) satisfies all critical matching parameters. Both components are active products with RoHS3 compliance and operate within the identical temperature range of -55°C to 125°C.

Parameter Comparison

Engineering Selection Recommendations

Both the BK/AGC-V-1-R and 0318001.HXP are active products with full RoHS3 compliance and established approval certifications. The Eaton component carries CSA and UL certifications, while the Littelfuse substitute carries expanded certifications including CE, CSA, KC, PSE, and UL.

Selection between these components should be based on:

1. Certification Requirements: If your application requires CE, KC, or PSE compliance in addition to CSA and UL, the 0318001.HXP provides broader regulatory coverage.

2. Inventory Availability: Both components maintain adequate stock levels (857 pcs for Eaton, 789 pcs for Littelfuse).

3. Electrical Characteristics: While both components meet the critical electrical parameters, the DC cold resistance and melting I²t values differ slightly. The BK/AGC-V-1-R exhibits lower DC cold resistance (0.167 Ohms vs. 0.19 Ohms) and higher melting I²t (3.24 vs. 0.76).

4. Physical Dimensions: Dimensional tolerances are minimal (Eaton: 0.266" Dia x 1.292" L; Littelfuse: 0.275" Dia x 1.288" L) and fall within standard 3AB, 3AG package specifications.

Frequently Asked Questions (FAQ)

Q: Can the 0318001.HXP directly replace the BK/AGC-V-1-R in my circuit?

A: Yes. Both components are 1 A, 250 V AC/DC fast-blow glass cartridge fuses with identical package specifications (3AB, 3AG, 1/4" x 1-1/4"), mounting type (through-hole), and breaking capacity (35 A). They are electrically and mechanically interchangeable.

Q: What is the significance of the different melting I²t values?

A: The melting I²t parameter describes the thermal energy required to melt the fuse element. The BK/AGC-V-1-R has a melting I²t of 3.24, while the 0318001.HXP has 0.76. Both values are within the fast-blow fuse classification for 1 A rated components and do not affect substitution eligibility for this application category.

Q: Are there differences in approval certifications between these parts?

A: The BK/AGC-V-1-R carries CSA and UL approvals. The 0318001.HXP carries CE, CSA, KC, PSE, and UL approvals. If your application requires international certifications beyond CSA and UL, the Littelfuse component provides additional compliance coverage.

Q: Do the physical dimension differences matter?

A: No. Both components conform to the 3AB, 3AG standard package format. The minor dimensional variations (Eaton: 0.266" Dia x 1.292" L; Littelfuse: 0.275" Dia x 1.288" L) are within standard tolerance ranges and do not affect mechanical fit in standard fuse holders.

Q: Which component should I select for new designs?

A: Both components are active products suitable for new designs. Selection should be based on your specific certification requirements, preferred supplier relationship, and inventory availability. The broader certification coverage of the 0318001.HXP may be advantageous for applications requiring international market compliance.
